Dracaena Plant Named &#39;KKDR201205&#39;

ABSTRACT

A new and distinct  Dracaena  cultivar named ‘KKDR201205’ is disclosed, characterized by distinctive foliage variegation pattern unlike other known  Draceana reflexa  cultivars, as well as narrow leaves. The new variety is a  Dracaena , typically produced as an indoor ornamental plant.

LATIN NAME OF THE GENUS AND SPECIES

Dracaena reflexa

VARIETY DENOMINATION

‘KKDR201205’

BACKGROUND OF THE INVENTION

The new cultivar is the product of chance discovery. The new variety originated as a naturally occurring whole plant mutation of an unnamed, unpatented variety of Dracaena reflexa.

The new variety was first discovered by the inventor, Kanchana Khemakongkanond, a citizen of Thailand, in February of 2005, in a nursery in Bangkok, Thailand. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘KKDR201205’, assessing stability of the unique characteristics of this variety.

Asexual reproduction of the new cultivar ‘KKDR201205’ was first performed by vegetative cuttings at the same nursery in Bangkok, Thailand during July of 2005. Subsequently at least three generations have been produced from vegetative cuttings, and have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘KKDR201205’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KKDR201205’. These characteristics in combination distinguish ‘KKDR201205’ as a new and distinct Dracaena cultivar:

1. Distinctive foliage variegation pattern unlike other know Draceana reflexa cultivars.

2. Narrow leaves.

PARENT COMPARISON

Plants of the new cultivar ‘KKDR201205’ are similar to the unnamed, unpatented Dracaena reflexa parent, in most horticultural characteristics. The new variety, however, produces larger, variegated foliage, whereas the parent produces smaller, green leaves.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘KKDR201205’ can be compared to the commercial variety Dracaena ‘Song of India’ unpatented. The two Dracaena varieties are similar in most horticultural characteristics; however, ‘KKDR201205’ produces larger leaves with a variegation pattern not found in plants of ‘Song of India’.

Plants of the new cultivar ‘KKDR201205’ can also be compared to the commercial variety Dracaena ‘Anita’, unpatented. The two Dracaena varieties are similar in most horticultural characteristics; however, ‘KKDR201205’ has variegated foliage whereas plants of ‘Anita’ produce green foliage.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘KKDR201205’ grown in a commercial greenhouse in Honselersdijk, the Netherlands. This plant is approximately 8 months old, shown planted in 12 cm. containers. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
